Ore processing consists of removing impurities, engineering particle ...
Firing is the most important manufacturing process stage, because, when the semi-hardened elements travel through the kiln, they undergo fundamental transformations in their physico-chemical properties. The processed pieces are subjected to a high-temperature thermal cycle up to 1300 C. The length of the kiln can be more than hundreds of meters.
